A 38-year-old Dickinson man is in custody this afternoon after making a threat to commit an act of violence at City Hall. Police received a tip from the North Dakota Bureau of Criminal Investigation regarding a text message allegedly written by the man indicating he was intending to bring a handgun into the municipal courtroom during a hearing.

Police identified the man as DEREK MITCHELL DECKER and notified City Hall of the threat. As a result, a decision was made to close City Hall for the remainder of the day while the threat was being investigated.

DECKER was scheduled to appear in municipal court at 10:00 AM for arraignment on pending charges of Criminal Mischief, Criminal Trespass, and Disorderly conduct.

Around 10:05 AM, officers who were conducting surveillance on DECKER’s residence observed him enter a vehicle and begin driving towards City Hall. A traffic stop was conducted and DECKER was detained without incident. DECKER admitted to having a revolver in the vehicle, which was located and seized by officers. DECKER was ultimately arrested and will face charges of Terrorizing in Southwest Judicial District Court.

“It’s instances like these that prove the importance of ‘See Something, Say Something’ cooperation from the public,” quoted Dickinson Interim Police Chief Joe Cianni. “This tip undoubtedly prevented what could have been a very serious and violent situation. We commend city staff for their quick actions to secure the workplace, and also thank our officers for their investigative skill and quick thinking to bring the incident to a successful outcome.”

DECKER is currently being housed at the Southwest Multi-County Correctional Center awaiting a bond hearing.
